To enable the automatic voltage 34 compensation for vdd mpu and vdd core from user space, 35 user must write 1 to 36 /debug/smartreflex/sr_<X>/autocomp, 37 where X is mpu_iva or core for OMAP3. 38 Optionally autocompensation can be enabled in the kernel 39 by default during system init via the enable_on_init flag 40 which an be passed as platform data to the smartreflex driver. 41 42config POWER_AVS_OMAP_CLASS3 43 bool "Class 3 mode of Smartreflex Implementation" 44 depends on POWER_AVS_OMAP && TWL4030_CORE 45 help 46 Say Y to enable Class 3 implementation of Smartreflex 47 48 Class 3 implementation of Smartreflex employs continuous hardware 49 voltage calibration. 50 51config OMAP_RESET_CLOCKS 52 bool "Reset unused clocks during boot" 53 depends on ARCH_OMAP 54 help 55 Say Y if you want to reset unused clocks during boot. 56 This option saves power, but assumes all drivers are 57 using the clock framework. Broken drivers that do not 58 yet use clock framework may not work with this option. 59 If you are booting from another operating system, you 60 probably do not want this option enabled until your 61 device drivers work properly. 62 63config OMAP_MUX 64 bool "OMAP multiplexing support" 65 depends on ARCH_OMAP 66 default y 67 help 68 Pin multiplexing support for OMAP boards.

The 32KHz timer provides less 124 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is 125 currently only available for OMAP16XX, 24XX, 34XX and OMAP4/5. 126 127 On OMAP2PLUS this value is only used for CONFIG_HZ and 128 CLOCK_TICK_RATE compile time calculation. 129 The actual timer selection is done in the board file 130 through the (DT_)MACHINE_START structure. 131 132 133config OMAP3_L2_AUX_SECURE_SAVE_RESTORE 134 bool "OMAP3 HS/EMU save and restore for L2 AUX control register" 135 depends on ARCH_OMAP3 && PM 136 default n 137 help 138 Without this option, L2 Auxiliary control register contents are 139 lost during off-mode entry on HS/EMU devices.
